buffer to calculate the number of entries and CIEs. Allocate memory
for them before the main loop. Replace current extended cie
representation with a pair of pointers, one to the local eh_cie_fde
and one to the full struct cie. Allocate a separate array of struct
cies if not merging. Merge CIEs during the main loop and set up each
u.cie.merged field. Point an FDE's cie_inf field directly at the
local CIE. Initially assume that all entries should be removed.

already been parsed. Use a separate pass to mark entries that
need to be kept. Use the u.cie.merged field to track a CIE's
